I have used fins for many reasons as I continuously improve my swimming.
At present, the "underloading" feature of fins is helping me integrate my new early vertical forearm/high elbow catch-and-pull into my core rotation. The fins better anchor my kick, so that I can learn to time core muscle contraction with catch/pull. Retraining stroke timing is necessary because my new stroke requires MUCH less body roll than I originally learned in the stacked shoulder era.
I find that using fins and swimmer's snorkel, singly or in combination, allows me to re-integrate my technique.
